GlJ i$$ Tl ihlhi FURNACE...

To (all mil/(mt it WNW] concern:

Be it known that i, ANDREWO. HURLEY, a resident of New Bethlehem, in the county of Clarion and State of ifennsyl'vania, have invented a new and useful improvementin Glassllfanlr Furnaces; and l do hereby declare the t'rdlewiing to he a full, clear, and exact description thereof.

il'iy invention relates to glass-tank furnaces. in a patent granted to me on the 17th day of January 1899, No. 617,746, I have illustrated and described a certain improvement in glass-tank furnaces, the object of that invention being to increase the life of the furnace by protecting the Walls thereo'l from the action of the flux in the molten glass, which is liahlo to attack the refractory lining and disintegrate the same.

The present invention relates to an improve- 2 ment in the above invention; and it consists in the novel features hereinafter fully set forth and claimed.

To enable others skilled in the art to make use my invention, 1 will describe the same 5 more fully, to the accompanying referring drawings, in which" 7 Figure l is a side elevation of a glass-tanlr embodying my invention. Fig. 2; is a crosssection on the line 2 2, Fig. 1. Fig. 3 is a 3 plan view with a portion of the roof removed. Fig. i is an enlarged cross-section oi the water-tank and a portion of the furnace wall and root supported above the same, an 5 is a g'ierspective view oi. one of the pans for receiving the drippings or overflow from the water-tank.

My invention may he applied to diil'erent forms of glass-tank furnaces, as the arrangement of heating-lines, &e., forms no part of 4- this invention. l

The numeral 1 represents a glass-tank furnace having the rcgenerators 2, (shown in dotted lines,) located along the sides of the mrltirm-section, and having the ports 3, leading into said melting-section. These regenerators only extend along the melting-section, as it is in this section oi" the furnace that the high temperature is maintained for the melting operation. The furnace may he said to 5 be divided into the melting-section L and the of Letters Patent Getober 10,1903; Serial 'Llo. 176,502,

l gathering-section 5.

no. 792,705, dated June 20, 1905.

The gathering end has the regular gathering-ports 6. The root 7 is supported independently of roof being arched and supported at the sides upon the shelves .l, which are carried by hucltstaves 10, connected by tie-rods 11. By the ahovewonstruction the walls of the futhace may be repaired withoutinterfering; wi ,aid roof. v

The Walls of the furnace are made up of the water-tanks 12, said tanhs being arranged end to end and secured together in any suit ahle manner, the corners of the walls being made up of the corner-pieces 18. if desired, however, one continuous tank may he emi loyed instead of several tanks, as illustrated. .hese water tanlts 12, as indicated in time, are composed of metal plates riveted together and braced within hy angle-bars i i. The exteriors of the tanks are braced by means of the braces 15, bolted to a suitable floor or foundation. The inner walls of the tank 12 have the vertical portion 16 and the inclined portion 17. To this inner wall are secured the wooden linings "18 by tl'ioholts 19. lfhe upper portion of the inner plate i7 is shaped, as at 20, to form the groove or depression 21, which extends aloug" the top of the tank. The top of the tank open, as at 22, and extending into this opening is the supply-pipe 23 for supplyingwater to the tank. A valveil i controls the pipe 23'. The overflow-pipe 25 is provided. Depending from the roof 7 is the longitudinally-extending rib or extension .36, which )roects into the qroove 2i.

Beneath the tanks 12 are the pans 2?,ivhich are adapted to receive any drippings from the tanks.

\Vhen my improved glass-furnace is in use, thh hatch for forming the glass is introduced into the front end of the Furnace, and the furmice is then heated up to the proper temperatureto melt the batch, which gradually resolves itself into a molten muss. As thetemperature increases the glass heeomes thinner and ilows toward the gathering end. The adjacent to the side walla or \Vfl.l]Ul'--ldtl'll(8 will become chilled hy the action of the water and alayer of chilled glass will he formed along the sides of the furnace, as indicated in the walls, salt.

an exaggerated'form at 28, Fig. 2. The wooden cooling fluid will be to cause the chilling of the glass, as stated, along the sides of the tank. The molten glass will enter the grooves 21 and will become chilled by Contact with the metal, asv indicated in ,Fig. 2. This portion of the chilled glass within the groove 21 will actto bind or look the layer of chilled glass extending down along furnace. The depending projections 26, entcringv the grooves 21, will, in connection with this chilled portion of the glass in the grooves 21, act to seal thesides of the tank and prevent the escape of the heat. By having the inner walls of the tank slightly inclined, as at 17, the slipping of the glass is further pie vented and greater opportunity is given the glass to chill and form the protecting-coverand, furthermore, said plates have a circulatlining 18 may-become burned or charred by the heat of the furnace; but the effect of the the sides of .the tank and prevent its slipping down, as might 00-,

vid our in the case ofvertical inner walls in the ing stream of water constantly in contact therewith, which keeps them cool.

What I claim is '1. A their interior faces extending up vertically outwardlyfrom that point, and a groove or depression formed in said walls beyond said glass.

'2, A glasstank furnace having walls proed with a groove or depression extending longitudinally thereof along the upper. edge "of said walls adapted to receive the molten glass, means groove, a roof supported independently of said walls, and a dependingrib on'said roof adapted to enter said groove.

3. In a glass-tank furnace, a metal tank forming the wall of the glass-melting compartment of said furnace, the inner plates of said tank extending vertically from the-bot tom for a distance, and inclining outwardly from that point, and agroove or depression ROBEBT (J. TO'ITEN,
